Abstract: 396,988. Wrappers; packages. ANDREWS, O. B., 605, Fairy Trail, Fairyland, Lookout Mountain, Chattanooga, Tennessee, U.S.A. Dec. 3, 1932, No. 34304. [Classes 94 (i) and 94 (ii).] A package for a loaf of sliced bread is adapted to be unsealed at one end to permit slices to be removed, and the remainder can be maintained in their relative positions when the packet is reclosed. Before enclosure in a tubular wrapper with end folds, the slices 6 are encircled by a band 10 having a series of tongues 12 adapted to be engaged by a hook 13. The position of the loaf is defined by a crease 16, and scored lines 17, 18 facilitate bending to conform to the size of the loaf. As slices are removed, the hook 13 is progressively engaged with slots 11, 15 to compensate for the decrease of the remainder, and a second hook portion formed by a slot 25 may be brought into use, the hook 13 being removed by tearing along the line 26. When the banded loaf is to be wrapped, and in order to prevent the edges on the underside from sagging and being fouled by the folders, an arcuate portion 20, Fig. 5, is cut away, so that the line 19 of the greatest stress is tangential thereto, and the other edge 22 is provided with a crimp 23 to achieve a similar result. In a modification, both edges may have smaller arcuate cuts. United States Specification 1,840,425 is referred to.

Filed: 1972-07-27
Abstract: 1395374 Cinematography EASTMAN KODAK CO 27 July 1972 [2 Aug 1971] 35178/72 Heading G2E Within a cine camera there is provided a drive mechanism for powering from a single motor (not shown in Fig.1) the movement of a lens element 16 of the camera's objective lens 12 and a cam 80 powering an intermittent claw film feed. Both may be operated separately or simultaneously. As shown in Fig.1 the motor has a drive-shaft carrying gears 34, 96. The zoom lens 12 is powered from gear 34 through fixed gears 38, 52 on a shaft 40. The shaft 40 also supports a pivoting plate carrying gears 48, 50 which mesh with each other and gear 48 also meshes with gear 52. By pivoting the plate 42, by means of rocker switch 62 either of the gears 48, 50 can engage gear 30, which drives the rack mounted lens element 16, and drive it in opposite directions. The film drive cam 80 is engageable by either gear 90 or 92, these being driven by the gears 34, 96 respectively. The gears 90, 92 correspond to passing speeds of 9 and 18 f.p.s. respectively. The passing speed selector control button 120 either tab 95 or 97 into slot 102 or 104 on plate 100 attached to slider assembly 114. Movement of the plate 100 towards the right upon movement of the slider 114 will, as shown, rock plate 94 about motor shaft 36 so that gear 92 will mesh cam 80.  To expose a film trigger lever 140 is depressed thereby moving the slider 114 and hence connecting either gear 90 or 92 to the cam 80. Depression of the lever 140 also moves lever 162 about pin 132 against the action of spring 166. This is due to abutment of surfaces 154, 168. The lever 162, in so moving, closes switch SW2 to power the motor and moves tab 164 from a radial recess 88b into the circular portion 88a of a rebate 88 in the cam 80 to permit the cam 80 to rotate. An interlock is provided by surfaces 176, 177 to ensure that the slider 114 is moved before the lever 162. At the end of an exposing sequence surfaces 176, 178 prevent the slider 114 returning to the position shown before the return of the lever 162. The recess 88b engaged by the tab 164 is provided to ensure that when filming stops the film drive is stopped with the camera shutter closed. When the camera is filming the zoom lens element 16 can be powered by rocker switch 62 pivoting the plate 42 as described without any energizing of the motor being required. When the  camera is not filming then a switch SW1 also moved by the switch 62 energizes the motor. The switch SW 1 is in series with switch SW4 which is closed only when the trigger lever 140 is not depressed. On pressing the lever 140 SW4 is opened and switch SW3 closed. SW3 controls an automatic exposure control device. With SW3 located as shown, depressing the lever 140 closes SW3 before SW2 so ensuring that the first film frame is correctly exposed.
